Been changing trains at Clapham for nearly 50 years now and have hardly ever noted a Battersea movement while awaiting my Portsmouth line trains, despite the frequency being nearly once a fortnight in the last few years. This morning four movements in not much more than five mins... Bell Mega Ranger out, AW139 in, A109 in and almost straight out again... RAF Atlas over the top just as I boarded and a USAF C-12 westbound over London at the same time.
